Modifying Footnote Plugin for Descriptive Title Attributes

I’ve been struggling for a couple hours now to get this working… Hopefully someone here can help me.

I just started using the wp-footnotes plugin, and I’m trying to set the title attribute on backlinks to “Return to footnote # in the text.” where # = the footnote number.

Below is what I tried, putting the $id_num variable in the title attribute, but it ends up just displaying as the number of footnotes that exist. You can see this at my development site on the first post.

Thank you so much in advance for any help.

It’s quite a bit, so I’ll paste the code in at the end:

    // Display identifiers      
    foreach ($identifiers as $key => $value) {
        $id_id = "identifier_".$key."_".$post->ID;
        $id_num = ($style == 'decimal') ? $value['use_footnote']+$start_number : $this->convert_num($value['use_footnote']+$start_number, $style, count($footnotes));

        $id_replace = $this->current_options['pre_identifier'].'<a href="'.$id_href.'" id="'.$id_id.'" title="'.$id_title.'">'.$id_num.'</a>'.$this->current_options['post_identifier'];
        if ($this->current_options['superscript']) $id_replace = '<sup>'.$id_replace.'</sup>';
    }

    // Display footnotes
    if ($display) {
        $start = ($start_number != 1) ? 'start="'.$start_number.'" ' : '';

            if ($style == 'symbol') {
                $data = $data . '<span class="symbol">' . $this->convert_num($key+$start_number, $style, count($footnotes)) . '</span> ';
            }
            $data = $data.$value['text'];
            if (!is_feed()){
                foreach($value['identifiers'] as $identifier){
                    $data = $data.$this->current_options['pre_backlink'].'
<a href="'.( ($use_full_link) ? get_permalink($post->ID) : '' ).'#identifier_'.$identifier.'_'.$post->ID.'" class="backlink"
title="Return to footnote '.$id_num.' in the text.">↩</a>'
.$this->current_options['post_backlink'];
                }

    return $data;
}
